L. viridiventris is a small orb-weaver spider with distinctive green coloration. Males have a body length of 3.08–3.44 mm, while females are larger at 3.88–5.44 mm. The
cephalothorax is brown and pear-shaped, slightly longer than wide. The opisthosoma is uniformly yellowish green without markings, which distinguishes it from the closely related
L. noegeatus. In living specimens, the abdomen appears fresh green, though this fades to grayish white in preserved specimens. Males can be distinguished by their
pedipalp structure, which has a single long bristle (macroseta) on the patella, and an elongated, S-shaped embolus that is wrapped by the conductor. Females lack a scape on the
epigyne, and the
spermathecae are almost touching. ==Habitat==
